The Secretary of Housing and Urban Development shall pay from rentals annual sums in lieu of taxes and special assessments to any State and/or political subdivision thereof, with respect to any real property, including improvements thereon, acquired and held by the Secretary under this subchapter for residential purposes (or for commercial purposes incidental thereto), whether or not such property is or has been held in the exclusive jurisdiction of the United States. The amount so paid for any year upon such property shall approximate the taxes and special assessments which would be paid to the State and/or subdivision, as the case may be, upon such property if it were not exempt from taxation and special assessments, with such allowance as may be considered by the Secretary to be appropriate for expenditures by the Federal Government for the provision or maintenance of streets, utilities, or other public services to serve such property.
